The thesis is divided into three distinct parts. The first part presents the beginnings of the discipline of bioethics and the course it followed until the formation of an independent discipline. Also it presents in detail the major problems in theoretical bioethics, concepts, principles and values used for the correct functioning, and the sociopolitical dimension necessarily stigmatizing any theoretical movement industry. Finally, it presents and discusses prevailing critical approaches bioethics.

The second part of the thesis deals with one of the major issues being addressed by bioethics but not studied in our country. This is the issue of education, in particular with the issue of ADHD and the pharmaceutical treatments that intrude into the lives of children. The issue of education is a very important topic of the thesis. In this case, it is considered that the role of bioethics is not limited to clarifying the very concept of mental disorder but that the value of bioethics approach, combined with the philosophical tools that it integrates emerges in this analysis in a tangible way.

The third and final part of the thesis applies the combined theoretical and practical approach considered appropriate in this interdisciplinary field to three different, key issues of bioethics. The first chapter addresses the key issue of genes and gene research which is an important focus of modern scientific studies.

The second chapter deals with the problem of death, an essential issue of medical science and practice, the central point of discussion in scientific research and technological developments.

The third and last chapter of the third part, discusses the issue of doping, and the use of doping for integration into an already configured institutional social context. Throughout the research it is clear that both the formation and the role of bioethics is largely dependent on social, economic and social choices of western societies.
